M5.1 Earthquake 164 km E of Petropavlovsk-Kamchatsky, Russia — April 24, 2026
2026-04-24 12:49:37 UTC (2 hours ago)
Aftershock of the M5.4 mainshock.
On April 24, 2026 at 12:49 UTC, a magnitude 5.1 shallow crustal earthquake struck 164 km E of Petropavlovsk-Kamchatsky, Russia, at a depth of 10.0 km and coordinates 52.9177°, 161.0719°. This earthquake was detected by 73 seismic stations with good location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.4 mainshock that occurred 5 hours ago 156 km E of Petropavlovsk-Kamchatsky, Russia. Since the mainshock, the USGS has recorded 3 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.
The epicenter is located in Russia, a region characterized by the Kuril-Kamchatka subduction zone on the northwestern Pacific Ring of Fire. The nearest mapped fault system is the Kuril-Kamchatka Trench. View all earthquakes in Russia.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.1 earthquakes can continue for days to weeks and gradually diminish over time.
Is this the same earthquake as the M5.4 one earlier?
No. This magnitude 5.1 earthquake is an aftershock of the larger magnitude 5.4 mainshock that occurred earlier 156 km E of Petropavlovsk-Kamchatsky, Russia. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
Has Russia had earthquakes this big before?
The largest recorded earthquake in Russia was the M9.0 Kamchatka earthquake of November 4, 1952. Today's magnitude 5.1 event is significantly smaller than that historical record.
What should I do after an earthquake?
If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
